Geoinformatics Interview Questions and Answers
Question - 11 : - What Is A Geographic Information System?
Answer - 11 : -
GIS is a system of computer software, hardware, data, procedures and personnel combined to help, manipulate, analyze, and present information that is tied to a geographic location.
Question - 12 : - What Is Gis Data Mining?
Answer - 12 : -
GIS or spatial data mining is the application of data mining methods to spatial data. Data mining, which is the partially automated search for hidden patterns in large databases, offers great potential benefits for applied GISbased decision making. Typical applications including environmental monitoring. A characteristic of such applications is that spatial correlation between data measurements require the use of specialized algorithms for more efficient data analysis.
Question - 13 : - What Is Spatial Etl?
Answer - 13 : -
Spatial ETL tools provide the data processing functionality of traditional Extract, Transform, Load (ETL) software, but with a primary focus on the ability to manage spatial data. They provide GIS users with the ability to translate data between different standards and proprietary formats, whilst geometrically transforming the data en route.
Question - 14 : - What Is Geostatistics?
Answer - 14 : -
Geostatistics is a branch of statistics that deals with field data, spatial data with a continuous index. It provides methods to model spatial correlation, and predict values at arbitrary locations (interpolation).
Question - 15 : - What Is Hydrological Modeling?
Answer - 15 : -
GIS hydrological models can provide a spatial element that other hydrological models lack, with the analysis of variables such as slope, aspect and watershed or catchment area.
Question - 16 : - What Is Gis Technologies?
Answer - 16 : -
Modern GIS technologies use digital information, for which various digitized data creation methods are used. The most common method of data creation is digitization, where a hard copy map or survey plan is transferred into a digital medium through the use of a CAD program, and georeferencing capabilities.
Question - 17 : - Which Of The Following Are Important Characteristics Of A Sdss?
Answer - 17 : -
- They are easy to use.
- They incorporate spatially explicit models.
- They are designed to make full use of available data.
Question - 18 : - Which Of The Following Are Examples Of Non-cartographic Output?
Answer - 18 : -
- Charts
- Tables
- Dynamically linked graphs
Answer - 19 : -
A set of graphs and maps where items are linked in separate displays.
Question - 20 : - What Does The Abbreviation Vrml Stand For?
Answer - 20 : -
Virtual Reality Modelling Language
